.thr ust the Shaft, s back through a;

posite parallel sides between which the stem, P of the housing may be entered with either pair of its two opposite sides adjacent the said parallel edges of the aperture, but without capacity for rotating while thus engaged. The intention. of this construction is to adapt the housing to be applied in either of two positions at right angles to each other, one of said positions being shown in Fig. 1 with the operating knob hereinafter mentioned protruding forward across the plane of, the dial, the other position being shown in Fig. 2, the resetting stem being positioned parallel to the dial with the knob or handle behind the dashboard. In the cross member of the "i" housing there is journaled the resetting shaft, Q, which is also adapted to slide longitudinally in its hearings in said housing. On this resetting shaft there is mounted for rotation therewith a beveled gear, Qfiwhich at one limit of the sliding movement of the resetting shaft, Q, meshes with a beveled gear, Q journaled in the end of the bearing of the shaft, E and-engaged with said shaft for rotation thereby by means of a pin, 6 in said shaft engaging a slot, Q2, in the hub of the gear, Q The resetting shaft, Q, has within the housing a conical cam, (.1 which is positioned for encountering the rounded end, a of the shaft, E which protrudes beyond the gear, Q for such encounter With-the care, the largerbase of the coneshaped cam is toward the gear, Q, so that when the shaft, Q, is pulled forward to draw the gear, Q into mesh with the gear, Q the cone-shaped cam, Q operatis to ingagainst the resistance of the spring, F,

of meshwith the, pinion, D "suit that when the gear,

in direction for carrying the gear, E, out

Q}, comes into mesh with the gear, (2?, the trip counter train has no driving engagement except the engagement, of the gears, Q and Q and is free to be operated for resetting by the rotation "-of the resetting shaft, Q. When the resettin shaft is thrust in the opposite direction, t e spring, F, -returns the shaft,

E to position,;-for E, with thepinion, D I tioning the gear, Q at its engagement with the gear, Q and for likewise definitely positioning it out of engagement with said gear, Q the resetting shaft,,Q,,has grooves, g and respectively at the larger and smaller bases of the cone cam, the grooves being shaped to seat the rounded end of the shaft, E", at the two positions indicated, the/rounded end of the shaft and the corengagmg the gear,

responding shape of the grooves permitting [the engagement necessary resetting shaftl from one position to the other.

In the modified form of the device indiwith the re For definitely fiposr 1 for moving the.

meagre cated in Fig. 6, instead of the square stem shown in 3 and 4, the stem of the housing, P, is cylindrical as shown at P in said Fig. (3, and the case, A, may then have a circular aperture, (1. as shown in said figure. Thus constructed, the housing is susceptible of adjustment to any position about the of the shaft, E and not limited to the two positions at right angles to each other which are shown in Figsl and 2, respectively. In this modified form the housing may be secured at the selected position of the bearing, 6 by a set screw, S. Preferably, two seats, 8, are provided in the periphery of the bearing, 6 for engagement by the set screw, S, at the two most usually desired positions at right angles to each other. But it will be understood that the housing may be set at any other position, the screw impinging upon the bearing for securing the housing.

1. In a revolution meter, a manually-operable device for operating or resetting the indicating train, comprising in combination with a prime operating shaft of said train, a shaft transverse thereto; a housing in which said transverse shaft is journaled, said housing being mounted for rotation about the axis of the prime shaft, and said transverse shaft protruding from said hou ing for manual operation, and inter-meshing gears on said shafts respectively within the housing.

-2. In a revolution meter, a manually-operable device for operating or resetting the indicating train, comprising in combination with a prime operating shaft of the train, a shaft transverse thereto; a housing in which said transverse shaft is journaled, said housing being mounted for rotation about the axis of the prime shaft, said transverse shaft being protruded from said housing and exteriorly provided with means for manually rotating it, and intermeshing gears on said two shafts respectively Within the housing.

3. In a revolution meter, a manually-operable operating or resetting device, comm prising in combination with the prime op erating shaft of the indicating train a shaft transverse thereto; a housing in which said transverse shaft is journaled and from which it protrudes for manual operation, the housing being mounted for rotation about the axis of the prime shaft; intermcshing gears on said shafts res ectively within the liousing, and means for efinitely positioning said housing at re-determined points in its rotation about tfie prime shaft.

4. In a revolution meter, in combination with a case, a counter train mounted therein; a resetting device comprisin in combination. with a prime operating laft of the counter train a shaft transverse thereto; a

housing in which said transverse shaft is journaied; ans by which said transverse shaft is rotated said housing, and inter meshing rs on said two shafts Within said housing; said housing having a stem ransverse to said transverse shaft and beng mounted by means of said stem for rotation about the hearing of the prime soot n and the having 41 non-circular op through which said stem protrudes rnaling on said prime shaft bearing.

a revolution meter, in combination with a and a counter-train mounted therein, a resetting device comprising in combination with the prime shaft of said counter train, a shaft transverse thereto; a housing in which said transverse shaft is journaied and from which it protrudes for manual operation; intermeshlng gears on said. respectively Within said 1 ,7 the housing having a stem trans- Whic '1 is journaled therein gnounted by means of said stem n about the hearing of the prime said stem having two flat sides and 1t angles to each other, equally distant from the of the shaft, and the having an opening through Which said stem protrudes for en agement with the prime hearing, sai opening having one straight edge at substantially the same distance from the axis of the prime shaft said fiat sides of the housing stem;

whereby housing is adapted to be on 5 said being non-circular in crossgear on the train shaft at the longitudinally slidable, the train shaft protrudmg into said housing; intermeshing gears on said. tWo shafts respectively within the housing, disengageable by the sliding of said transverse shaft in said housing; a conical campn said transverse larger and smaller ends of said conical cam; the prime shaft having a rounded terminal adapted to engage said grooves and to be encountered and actuated by said conical cam upon. the longitudinal actuation of said transverse shaft, for forcing said train shaft longitudinally in its bearing and holding the transverse shaft yieldingly at the respective limits of its longitudinal movement; the gear on the transverse shaft being posifor intermeshing with the tloned thereon limit of the movement of said the train shaft is setting action.
